I had my one hour glucose tolerance screening this morning. I had to drink the drink in 5 minutes - it was really cold and not that bad. I chose orange. I also had a choice of lemon/lime - I decided to go with the orange since that was what I had been anticipating. It was a little sweeter than summer camp "bug juice".
After one hour, they pricked my finger and ran the blood glucose level and I found out immediately that I passed I needed to be less than 140 mg/dL and I was 118.
